Description

Version:

Made of high-tensile tool steel (> 1300 N/mm²). In conjunction with the convex insert clamping, the system achieves very high resistance to axial and radial cutting forces and thereby significantly increases the surface quality and productivity.

Note:

Coolant transfer only possible in conjunction with GARANT Master Eco toolholders No. 319006 − 319136.
From groove width 6 mm at t_max (5×groove width), the second cutter comes into contact with the workpiece. This can lead to scoring. Reliably free of scoring up to t = 24.5 mm.
